Commit Message

Use Web Audio API for volume fading if available

Setting `volume` in an interval has performance issues and can lead to
popping/sizzling noises on Firefox.

* Add `getMediaElement` method to media players to allow accessing the
  underlying media element. This required use the players as audio
  source.

* Add a Pageflow API to create a shared `AudioContext`. There can only
  be a limited number of contexts in one page (i.e. 6 in Chrome, at
  the time of writing). So allow reusing it for all Pageflow features.

* If an `AudioContext` can be created, connect a gain node and use its
  methods to perform volume fading.

* On Chrome and Firefox, the `crossorigin` attribute needs to be set
  to `anonymous`, to allow `AudioContext` usage for cross origin audio
  files. Since `audio5js` is already patched, make adding the
  attribute the new default.
